Additional preview pages of the HM5425801B datasheet.

The HM5425161B, the HM5425801B and the HM5425401B are the Double Data Rate (DDR) SDRAM devices.

Read and write operations are performed at the cross points of the CLK and the CLK.

This high speed data transfer is realized by the 2-bit prefetch piplined architecture.

2.5 V power supply SSTL-2 interface for all inputs and outputs Clock frequency: 143 MHz/133 MHz/125 MHz/100 MHz (max) Data inputs, outputs, and DM are synchronized with DQS 4 banks can operate simultaneously and independently Burst read/write operation Programmable burst length: 2/4/8  Burst read stop capability Elpida Memory, Inc. is a joint venture DRAM company of NEC Corporation and Hitachi, Ltd. HM5425161B, HM5425801B,.
